SFR1810zz Bearing Product Overview & Core Advantages
The SFR1810zz is a single row deep groove ball bearing designed for precision applications requiring reliable performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact inch dimensions (0.3125" bore) and shielded design make it ideal for applications demanding protection from contaminants while maintaining high limiting speeds up to 36,000 rpm. This bearing is engineered to handle primarily radial loads efficiently in a wide temperature range.

SFR1810zz Bearing Structural Features & Performance Benefits
Deep Groove Raceway & Single Row Design: The optimized raceway geometry enables smooth operation and efficient handling of radial dynamic loads up to 94 lbf.
Full Complement Stainless Steel Construction: All components, including rings, 12 balls, cage, and shields, are made from stainless steel, ensuring consistent performance and superior corrosion resistance in harsh environments.
Shielded (Non-Contact) Sealing: The 300 series stainless steel shields protect the internal components from debris without significant friction increase, contributing to the high limiting speed.
ABEC1 Precision Class: Manufactured to ABEC1 tolerance standards, ensuring reliable and consistent operation for a wide range of industrial applications.
MC3 Radial Internal Clearance: The specified clearance (0.00008" to 0.0005") is suitable for most general applications, accommodating thermal expansion and ensuring smooth rotation.
SFR1810zz Bearing Typical Application Areas
- Medical and Dental Equipment: Pumps, handpieces, and small precision instruments requiring corrosion resistance and reliability.
- Food and Beverage Processing Machinery: Conveyors and mixers where washdown and corrosion are concerns.
- Small Precision Motors and Gearboxes: Used in high-speed spindles and fractional horsepower motors.
- Office Automation Equipment: Printers, scanners, and copiers for precise shaft guidance.
- Instrumentation and Control Devices: Guidance systems and encoders where compact size and smooth operation are critical.
